Abstract
A capacitor comprising a tantalum or tantalum alloy electrode as one of the electrodes with an outgoing lead wire composed of a novel niobium alloy. According to the present invention, a capacitor having good heat resistance property can be inexpensively provided without reducing the capacitance.</SD OAB>
Claims (5)
1. A capacitor comprising two electrodes at least one of which is composed of tantalum or an alloy thereof and a dielectric material interposed between these electrodes, wherein an outgoing lead wire connected to the electrode is composed of a niobium alloy.
2. The capacitor as claimed in claim 1, wherein the niobium alloy is an alloy with at least one element selected from the elements belonging to Groups 2 to 16 of the periodic table.
3. The capacitor as claimed in claim 1 or 2, wherein the niobium alloy is a partially nitrided alloy.
4. The capacitor as claimed in claim 3, wherein the nitrogen content of the partially nitrided niobium alloy is from 20 to 150,000 mass ppm.
5. The capacitor as claimed in any one of claims 1 to 4, wherein the electrode connected with the outgoing lead wire has a sintered body structure and the CV value thereof is at least 40,000 (CV/g) or more.
